LEAK-STOPPER.

Specification of Letters Patent.

Patented Oct. 22,1912.

Application filed October 23, 1911. Serial No. 656,273.

To all whom it may concern:

Be it known that I, MARK E. SHERLAND a citizen of the United States,residing at lWIcGehee, county of Desha, and State of Arkansas, haveinvented certain new and useful Improvements in Leak-Stoppers, of whichthe following is a specification.

This invention relates to leak stoppers;

The invention has for its object the provision of a leak stopper ofnovel construction having means whereby it may be temporarily held inposition until the nut can be applied thereto; will be constructed in anew manner, where necessary or desired, so that it may be used as anoutlet or cap; and to provide, as a part thereof a sleeve nut adapted toclamp or secure the stopper in position and to enter the boiler platesin a new manner and to be used separate from, or in connection with, acap.

In carrying out the invention the features above enumerated need not allbe included in one embodiment of the device, the invention beingsusceptible of various modifications, as will appear more fullyhereinafter.

In the accompanying drawings :Figure l is a vertical section through oneform of the invention; Fig. 2, a similar view of a modification; Fig. 3,a view showing the manner in which the bolt may be held to permit theapplication of the nut; Fig. 4:, a perspective detail of one of thehalves of the bolt; Fig. 5, a vertical section of another modification;Fig. 6, a similar view of a further modification; and Fig. 7, aperspective of one of the halves of the bolt of Figs. 5 and 6.

In the practical embodiment of my invention, I provide a repair bolthaving its bolt proper comprising two half-round bolt parts 1 threadedon their outer curved surfaces, and provided with abutting fiatsurfaces. The bolt parts 1 are provided with extensions 2 at rightangles thereto. The bolt parts 1 are further provided with openings 3transversely therethrough adjacent their upper ends adapted to alinewith one another when said bolt parts are assembled with their flatfaces abutting one another.

In the practical embodiment of my invention and when there occurs a leakor small opening in boiler sheets, tubes or the like A, said leak isreamed out to form a substantially circular opening B of a desireddiameter which may or may not have a countersunk portion C formed in theeX- ternal surface of the part A adjacent said opening depending uponthe style of nut desired to be used in connection with said bolt. Theopening B is preferably reamed to a diameter substantially greater thanthe diameter of the combination bolt parts 1 to insure of the readyinsertion therethrough of said bolt parts and their angular extensions2, to the position shown in Fig. 3, when a wire or the like D may beinserted through the alined openings 8 and given a half turn around saidbolt parts in order to hold the same in positionwhile the nut is startedthereon. The enlarged diameter of the opening B permits of theinternally thread- .ed sleeve portion 4 of the several nuts to extendinwardly between said bolt parts 1 and the wall of said opening B, withits edge resting upon the angular portions 2. The nut may be in the formshown in Figs. 1 and 3 in which the same is provided with a circularoutstanding beveled flange 5 adapted to engage within the countersunkportion C, between which countersunk portion and said beveled flange awasher 6 may be disposed, said nut being provided with a squared closedupper end 7 above said flange by which the same may be screwed intoposition. The nut, on the other hand,

may be of the form shown in Fig. 2 in which the same is provided with anenlarged closed head 8 having a washer 9 disposed between the same andthe part A about the sleeve portion 4.

In the modification shown in Figs. 5, 6 and 7, I provide the flatsurfaces on each of the bolt parts 1 with longitudinally extendingsemicircular grooves 10 to form a substantial circular opening 11 whensaid parts are assembled in position so that the device may be used as atap. In this form I provide clamping means comprising sleeve nuts 12 andcap nuts 18. In the form shown in Fig. 5 the sleeve nut 12 extendsdownwardly between the bolt parts 1 and the wall of the opening B in thepart A and is provided with a circular outstanding beveled flange 1 1corresponding to the flange 5 on the nuts shown in Figs. 1 and 3 andadapted to enter a countersunk portion similar thereto. The cap nut 13closes the end of the bolt and its opening 11, being readily and easilyremoved in case a tap is wanted for any purpose. The form shown in Fig.

8 of the form shown in Fig 2, said enlarged head bearing upon thematerial of the part A surrounding its opening B. The cap nut 13 issimilar to the one employed in Fig. 5 and closes the end of said boltand its opening 11 and may be similarly removed when desired.

Having thus described my invention, what I claim as new and desire tosecure by Letter's Patent, is:

1-. In a leak stopper for boilers, pipes, '01- the like, the combinationof a pair of bolt parts having abutting flat faces, having angularextensions at one end thereof, and having their outer curved facesthreaded up tosaid extensionaand a tubular nut adapted to be screwedupon the threaded ends of said bolt parts, and to abut said angularextensions, said nut having an outstanding port-ion.

2. In a leak stopper for boilers, pipes, or the like, the combinationofa two part bolt proper, each of said part-s having an angularextension at one end thereof, and means for clamping said boltcomprising a sleeve nut to screw about said parts, and having anoutstanding portion adapted to enter a'recess in the boiler, pipe, orthelike to which the stopper is secured, and a cap nut to screw upon theend of said bolt against said sleeve nut. V

3. In a leak stopper, the combination of a two part bolt proper, each ofsaid parts having a semicircular groove to aline with the groove in theopposing part and to form an opening through the bolt when said partsare assembled each of said parts being furthere provider with an angularextension at a bolt composed of independent members each of angularform, the corresponding legs of which are screw threaded, of a nutadapted to engage the screw threaded legs and to clamp them together,said nutand screw threaded legs being so constructed and related thatthe nut is adapted to surround the legs where they pass through themember to which the leak stopper is applied.

5. In a leak stopper, the combination with independent angular memberseach havlng a leg provided with screw threads and both having flattenedabutting faces, said legs belng PIOX IdGd with ahned transverseapertures adapted for the reception of a temporary holdmg member, of anut adapted to clamp the par-ts of the shank together and secure theangular members in position.

In testimony whereof, I hereunto affix my signature in presence of twowitnesses.
